LUBRICATING APPARATUS.

Application led April 27,

Our invention relates to improvements in ,lubricating apparatus,` and is particularly concerned with the provision of novel means for supplying lubricant under high pressure to bearings to be lubricated.

The objects of our invention are First: to provide a novel compressor for supplying lubricant under pressure to bearings, comprising means ior receiving a standard container of lubricant, and withdrawing the lubricant therefrom and deliver ing it to the bearings without the i'iecessity ot' first transferring the lubricant from the container to the compressor, as is now the usual procedure; y

Second: to provide a compressor of the character described which is adapted to receive lubricant containers ot' comparatively large capacity;

Third: to provide a compressor such as described in which atmospheric pressure is used for securing the container to the compressor in sealed relation, thereby doing away with the necessity oit' cylinders, clamps, and other similar means for holding the container in place; Fourth: to provide a compressor of the character described, which is simple in construction, economical to manufacture, easy to operate, and which may be easily carried by the operator;

Fifth: to provide a novel cooperation between a lubricant-container anda pump for receiving and. expelling the contents of said container, whereby the operation of the pump holds the container in place.

Other objects of our invention will appear as this description progresses, reference being had to the accompanying drawings, in which Figure 1 is a vertical central section through a compressor embodying our invention, and

Figure 2 isa horizontal section taken on line 2-2 of Figure 1. A I.

The embodiment of our invention illustrated in the accompanying drawings comprises a. substantially circular hollow base 5, the upper face ot which has a substantially circular conical depression provided with a central opening 6 and an inwardly extending annular shoulder 7 for 'supporting a screen 8. A circular gasket 9 Vis clamped between the bottom of the conical depression and the 1923. Serial N0. 634,945.

ring 10. This gasket has a horizontally extending flange 1l adapted to make sealed contact with the end closure l2 ot the container friction closure 15, shown in dotted outline in Figure 1. The two end closures l2 and 14 are provided with centrally located depressions lG for receiving the opposite ends of the guide rod 1T. A follower 18, preferably made ol wood, is slidably mounted upon the guide rod 17, and its diameter is such that the periphery thereof is slightly spaced from the walls of the container so as to avoid, as much as possible, any friction between the walls of the container and the follower;

A base plate 19 extends outwardly from one side of the hollow base 5, and the opposite side ot the hollow base is provided with a vertical extension 20 having a vertical bore therein, the lower portion 21 of which is larger in diameter than the upper portion 22. The upper portion 22 forms a high pressure cylin` der which con'm'mnicates with the chamber 23 in the hollow base 5 through the space 24 between the vertical extension 2() and the substantially concentric integrally formed wall 25. An opening 26 is cut through the wall of the smaller portion ot the bore to complete this communication.

The larger portion 21 of the bore `terms a valve chamber for the disc valve 27. which is yieldingly held against the shoulder 28, forming the end of the high pressure cylinder, by means of a compression spring 29 confined between the valve and the screw threaded plug 30 which closes the lower end et the enlarged portion of the bore. The periphery of the valve 27 is cut away at spaced intervals to provide passageways 31 between the valve and the adjacent wall of the bore through which the lubricant can pass.

The construction of this valve and of the high pressure developing means is clearly described and claimed in the co-pending application of Ernest W. Davis, Serial No. 634,970, filed of even date herewith, and

' forms no part of our invention, except as it co-acts with the remaining elements of our combination. U

The plunger 32 1s reciprocably mounted 1n the high pressure cylinder formed by the smaller portion 22 of the bore, and is of sufficient length to contact with and open the valve 27 when it is at the extreme end of its in stroke. For reciprocating the plunger 32, we provide. the` lever 33, one end of which is pivoted between the upper ends of two bifurcations 34 extending upwardly from the vertical extension 20, this pivotal connection being effected by a pivot pin 35. The free end of the lever 33 is provided with a handle 3G, by means of which it can be oscillated. .A link 37 has one end pivotally connected with the lever 33 intermediate its ends, by means of a pivot pin 38 which extends through the lever and bifurcations formed at the upper end of the link 37, and its other end is pivotally connected with the upper end of the plunger 32 by means of the pivot pin 39. A stop 40, carried by the link 37, adjacent its upper end, provides means for limiting the upward stroke of the lever 33 relatively to the remaining portions of the compressor.

A flexible discharge conduit 41 is connected With the end of the discharge nipple 42, which is formed integrally with the wall of the valve chamber and with the wall The discharge conduit 41 may, if desired, be providedA with a coupling member for making a sealed connection with a nipple or fitting secured to the bearing to be lubricated, but since this construction is well known to those skilled in the art, further description thereof is believed to be unnecessary.

In the operation of my improved lubricating apparatus, the operator removes the friction cover 15 from one end of the container of the lubricant, and punches or otherwise forms an opening 43 in the opposite end of the container so as to permit atmospheric `pressure to have access to the outer face of the follower 18. He then inverts the container, and places it over the opening in the upper face of the base 5. The operator then reciprocates the plunger 32 by means of the handle 36 and the connecting mechanism, whereupon the air contained in the'chamber 23 and the space between the vertical extensiomQO and the wall 25 will be rariied to such an extent that the atmospheric pressure pushing downwardly upon the outer face of the 4follower' 18 will cause the lubricant in the bearing to be lubricated. It will also be apparent that we have provided a novel container for t-he lubricant, and a novel lubricant package.

Having thus described our invention, what we claim is:

1. A lubricant compressor comprising a hollow base member having a circular opening in its upper side, a container resting upon said 'base member and communicating. with 75 said opening, a guide rod extending between opposite ends of said container, a. follower slidably mounted upon said guide rod, a gasket secured to said base member and interposed between said base member and said container for sealing the joint therebetween, said base member having a vertical extension adjacent one edge thereof provided with a vertically extending bore, the lower end of which is enlarged to provide a valve chamber and to form a valve seat intermediate the ends of said bore, means for establishing communication between said hollow base member and the smaller portion of said bore, a valve in said valve chamber, a spring for yieldingly holding said valve on said seat, a plunger slidably mounted in the smaller portion of said bore and of sufficient length to contact with and open said valve, an arm extending upwardly from said vertical extension, a lever having one end pivoted to said arm and extending over said container, a link connecting the upper end of said plunger with an iutermediate point on said lever, a handle secured to said lever at a point substantially above said container, and means for limiting the upward movement of said handle relatively to said arm.
